Drag tabs outside current window

Generally, I surf the web with my 2 monitors, myabe watching a video while doing something on the other screen. When I used firefox or chrome, it allowed me to open a new tab in one window and drag it to another open window, or open a new one without refreshing it (this happens when you right click->move to new window) but you can't move within windows wich I believe comes pretty handy and i something I miss from firefox

This is a problem because it reloads the tab.
The problem is when you're on a Google Hangout and you suddenly leave the call, only to show up a few seconds later and you missed part of the converstaion.
